Does your laptop have you singing the short-battery-life blues? If you've updated to Windows 10 Fall Creators Update, then you've got a new tool to help extend your laptop's running time. I'll cover this new tool along with some tried-and-true battery-saving tips.

Turn down display brightness

Powering all of those pixels in the display is the single greatest drain on battery resources. The first item to check when you are experiencing troublingly short battery life is your display brightness. If you've got it turned up all the way or near the max, then lower the brightness; you might also find it a more comfortable computing experience to your eyes.

Your laptop likely has two Function keys mapped to display brightness. If not, you can find a brightness slider by going to Settings > System > Display. You'll also find a slider for display brightness in the Windows Mobility Center, which is buried in the Control Panel; the easiest way to find it is just to search for it.

Paint it black

A bright desktop background requires your display's pixels to light up more, when requires more juice. Choose a dark picture or color by going to Settings > Personalization > Background.

Turn off keyboard backlights

Like the display, keyboard backlighting also drains your laptop's battery. Turn them off when they aren't needed. Your laptop likely has a Function key that lets you toggle the keyboard backlights on and off. If not, you'll find a control for it in the Windows Mobility Center.

Introducing the new battery slider

OK, now here's the new battery tool. Fall Creators Update has made it easier to switch between power modes. Instead of digging into the battery page in settings to switch from high performance to battery saver mode or vice versa, you now can just click or tap the battery icon in the taskbar. You'll be able to move a slider from Best battery life to best performance or a balanced mode in between.

Check power and sleep settings

Dig into Power & sleep settings by clicking its link in the battery menu from the taskbar (or by going to Settings > System > Power & sleep), and you can shorten the time before the display turns off or your laptop goes into sleep mode when it's running on battery power. The shorter you set these times, the longer your battery will last.

Use Battery Saver

Windows 10's built-in Battery Saver mode activates when your remaining battery dips below 20 percent. It disables email and calendar syncing, push notifications, and apps from running in the background. It should be enabled by default, but check to make sure it is by going to Settings > System > Battery. If you find that Battery Saver doesn't disrupt your regular Windows habits, then you can raise the threshold for when it activates above 20 percent.

Check Battery usage by app

You can see which apps are using the most battery resources by Settings > System > Battery and click Battery usage by app. The list will show you the percentage of battery your apps have used in the past 6 or 24 hours or the past week. If you find an app that you think it using more than its fair share, click on it and toggle off the switch for Managed by Windows and then make sure the box remains unchecked for Allow app to run background tasks.

These wireless networking technologies consume battery power. You can disable both by using Airplane mode. Click the Wi-Fi icon in the taskbar and then click the Airplane mode button. You can also disable only Wi-Fi by clicking the Wi-Fi button on the taskbar Wi-Fi menu. To disable Bluetooth, go to Settings > Devices > Bluetooth & other devices and toggle off the switch for Bluetooth.

Sync email less

Constantly checking for new email messages can drain your battery. So, tell Windows to check less frequently to extend the life of your battery. Go to Settings > Accounts > Email & app accounts. Click on your account, click the Manage button and then for Download new content, switch it from as items arrive to every 30 minutes, hourly or manually and then click Done.
